IndiGo controls a near 50 per cent share of the domestic aviation market.

Bengaluru:

A co-founder of India's biggest airline IndiGo, Rakesh Gangwal, said reports that a truce had been brokered between him and another co-founder Rahul Bhatia over disagreements on corporate governance were "false and misleading".

In a letter dated August 5, Mr Gangwal told the board of IndiGo's parent InterGlobe Aviation Ltd that issues between him and Mr Bhatia remained unresolved.

At the centre of Mr Gangwal's complaint were Mr Bhatia-controlled IGE Group's significant controlling rights over IndiGo, which he alleged allows them to carry out "questionable" transactions.

In the latest letter, disclosed by InterGlobe to exchanges on Tuesday, Mr Gangwal said he did not back a proposal by the airline to expand its board of directors to 10, arguing that it would benefit IGE and help it "rework and dilute" an agreed-upon policy on related-party transactions.

InterGlobe lost almost $1 billion in market value on July 10 after Mr Gangwal disclosed his complaint to regulators, although the shares have recouped most of those losses since then.

The stock rose around 2 per cent on July 24 after the Economic Times reported that InterGlobe chairman M Damodaran had brokered a truce between the co-founders.

Under Mr Gangwal and Mr Bhatia, IndiGo has grown rapidly since it launched flights in 2006 and now controls a near 50 per cent share of the domestic aviation market.

IndiGo, Asia's most valuable budget airline by market capitalisation, has also accelerated international expansion plans since Jet Airways, once India's largest private carrier, collapsed in April.
